Do sanity checking on a live SQLite3 database file specified by the
"database-filename" argument.

Options:

   --batchsize N     Number of rows to check per transaction

   --freelist        Perform a freelist check

   --index NAME      Run a check of the index NAME

   --summary         Print summary information about the database

   --table NAME      Run a check of all indexes for table NAME

   --tclsh           Run the built-in TCL interpreter (for debugging)

   --version         Show the version number of SQLite
